Actually, height and width are taken from the container of the tag specified. The body tag takes its width from the browser window width. The height of the body tag depends on which browser is used. IE uses the window height if the page fits, and the length of the rendered page if it doesn't. FF always uses the length of the rendered page.

If you want to develop your site for someone on a "1024px" width, then specify in CSS that the wrapper DIV will have that width. The same would be said for the height.

I change the size of my browser window to see how the page behaves at different resolutions.
